Hi there! Here's how I tackled the issue in a project I recently worked on:
function scrolling() {
var lastScrollTop = 0;
$(window).scroll(function() {
var current = $(this).scrollTop();
if (current > lastScrollTop) {
// downscrolling!
(put downscrolling stuff here)
} else {
//upscrolling!
(put upscrolling stuff here)
}
lastScrollTop = current;
});
}
Curious if others have better solutions...

sarboc thanks for your reply, I couldn't use your snippet because the handleLink function runs before the scrolling event, but it inspire me and I finally I came with this:
<a href="#slide4" data-menu-top="250"></a>
(position in percentage value without "p")
handleLink: function(link) {
var target=parseInt(link.getAttribute('data-menu-top')),//percentage position of target
currentTop = $(window).scrollTop();
currentTop=Math.round(sizes.bodyH()) * currentTop / 100; //convert to percentage
target=(currentTop < target) ? String(target+1)+'p' : String(target-1)+'p';
//console.log(target);
return target;//ex: 251p
},
Need to improve yet, sometimes that -+1p gives an undesired offset, but I achived the main goal that was to fire the event that high lights those links.
